Application filed March 18, 1914. Serial No. 825,452. v

Be it known that'I, FRIEDRICH BAL'rzER, a subject of the-Emperor of Germany, re- 3 siding at Berlin,-Germany, have invented? certain new and useful Improvements in- .Cages for Antifriction-Be'arlngs, of which the following is a specification, reference. being had therein: to the accompanying drawing. -1

This invention relatesto separators or cages for the rolling-elements of antifric-g tion bearings, adapted to be em loyed between the casing members of the bearing to maintain the rolling elements in spaced relations, and the inventionhas reference more particularly to that type of cage made up of annular connected sections providedin adjacent edges with recesses constitutingi seats .or'sockets for the rolling elementsl The inventionhas in view the production of acage adapted for use more articularly in connection with antifriction earings in which the rolling elements are in the "form a of balls, and the invention consists in an improved construction, comprising two an- F nularj sections disposed-1 edge to edge and formed in adjacent edges with recesses conjointly constituting ball seats, said sections having lips project ng therefrom at the'sides of the recesses,- by which the balls are embraced and held. I A

The invention-consists also in providing the annular sections between the recesses with tongues, those on one section being disposed alternately [on opposite sides of the'other section, the said ton es in order to admit of this arrangement eing-prefer-- ably oifset laterally in o posite directions relatively to'thebodyof t e'sections.

The invention consists'als'o in extending the ends of the tongues of one section beyond the outeredge of the-other section, and bending said tongues therearound to secure the sections together in operative relations.

The invention consists also in the details of construction and combination of parts hereinafter described and claimed.

In the accompanying drawings: Figuref'l is an elevation of one of the sections of the cage showing the same before it is bent into annular form; Fig. 2 is an edge view of the same; Fig. 3 is an elevation of aportion of the cage, showing the two annular sections assembled in operative relations preparatory to their being connected together; Fig. 4 1s 1 seats.

. a vertical transversesectional elevation on an antifriction bearing, showing in elevation aportion of my improved cage therein.

Referring to the drawings My improv ed cage comprises two annular sectlons e,

preferably of'thin sheet material, which are provided in their. edges with semicircular recesses f, f respectively, the recesses in one section being disposedo posite the recesses in the other section so t at when said sectlons are disposed edge to edge as shown in Fig. 3,'the opposing recesses will consti tute conjointly circular iopenin s or ball Between therecesses, t e an'milar sections are provided with tongues-k, lcrespectively, the tongues on each 'sectlon being ofiset laterally alternatelyin-oppositedirections relative to the body of t e section, so that when the sections are disposededge to edge as shown in Fig. 3, the tongues on each section will extend alternately on opposite sides of the other section, the W0 sections being firmly connected togetherin these relations by means of fingers 1 on the ends of the tongues which are bent downand around the outer edges of the sections tov asshown in Fig. 5. The sections'are pro-' vided-at opposite-sidesof the recesses therein, with lips z, i respectively, the lip on one side of a recess extendin in a direction opposite the lip on the ot er sideof said recess, this construction producing in eflect, pairs of lips on each section, WhlGl'l pairs project alternately in opposite directions from the opposite sides of the section as shownmore particularly in Fig. 2. In the assembled relation. of the parts of the cage as shown in Figs. 5'and 6, the balls seated in the openings h, are embraced on opposite sides of their center by the oppositely extending lips, which serve to retain them in the holes while permitting of their free individual rotation.

- In the formation of a cage 'of theconstruc- I tion described, two straight strips or sections of the form shown in Fig. 3 are provided and'are each bent into circular form,

assembledv together edge to edge as shown in Fig.3,- the endsof the two sections being interlocked by the engagement of shouldersuo inginembers'o I the two-sections being passed between the .10

, bearing, and as easily'disassembled when ocr enact, hef ds' of e-s s o in re ;c sses pwin'the' other ends','-t h1s interlocking {ends against axial displacement, relatively. In the assemblage of the cagesections onthe --will:'be' firmly connected together edge to cage" of the construction described may be produced economically and expeditiously in necessity of riveting, solderingor like perbut it will be understood that these-details may be' variously changed and modified of the eiids of the sections maintaining said ballswithin the bearing, the two sectionsjare insertedmfrom opposite sides, betweenthe cas- Y the'bearing, the tongues of baillsyiviththe tongues onone sect1on ex tending alternatelyon opposite sides of the other section.
